BTW the Summer of '42 was called the Focke Wulf Summer by the RAF.  This is because the FW-190 had complete domination in performance over the Spit Vb.  The RAF was so desperate to get ahold of an FW-190 and try to find a counter for it they accually planned and where about to launch a SOE operation to steal an FW-190 from a Luftwaffe base in France.

When Faber, thru a mistake in navigation, accidently landed on an RAF base in England the British got their FW-190.  They promptly tested it in every way possible looking for weaknesses.  The only advantage the Spit V had was turning.  And as one Spitdriver put it...TURNING DOESN'T WIN AIRBATTLES.  

Obviously he never flew in AH. :eek:

The Spit IX went a long way to closing that performance gap.  It matched the 190 in most areas and still maintained it's sustained turning advantage.  Matching is not dominating nor is an advantage dominating either.  Both aircraft had thier advantages over the other.  The areas the 190 held advantages were key ones though;  Manuverability, accelleration, and dive speed/level speed.

Crumpp


That about sums it up.  The LFIX caught the Spitfire up so it could compete with the 190.  The Spit V was totally outclassed.  

But that's how it worked.  Spit I.II vs 109E variants.  Then the 109F variants vs the Spit V variants.  190 shows up and upsets the applecart.  Spit IX lash up evens things out a bit.  190s go down low where the FIX isn't at it's best.  Typhoons rushed into service.  Tails come off a few.  Spit XII is introduced and the low level raids on England are curtailed because the XII can handle the 190 down low.

LFIX is introduced with max performance at a lower height band then the FIX where the 190s play, and in particular where the medium bombers fly in 43 over France.  Spit Vs are clipped clapped and cropped to provide some usefulness but still can't really keep up.

Spit XIV shows up along with the Tempest.  190D series appears a bit later.  109G10s, 14s Ks etc added to the mix to compete some more.  Of course the Jugs and 51s are also in this fight.

Just the nature of progress.

Anyone claiming the Spit V was an equal with the 190 is kidding themselves.  And the guys who fly against it in AH and let it fly to it's strengths pay the price because of that turning circle etc.

And in terms of AH we still should have an LFIX :)

Although this is a spit thread (or should be) I have to ask a question.

Crumpp, as for what I have made out from the 190 A5 Deck Speed thread, the conclusions in there have been that our 190 actually climb too good (judging from RLM charts) and that it is running on higher boost then it should due to a misstake in converting units.

So the spit should actually be even more superior to the 190 then it already is? So the fact that the 190 had a better zoom in R/L doesn't seem to apply in AH2 nor will it apply even if the 190 is changed, in fact, the spit will get more of an advantage over the 190 once it is changed...

Wilbus, our 190As (100% fuel and 4 guns) are matching more or less correctly the historical substained climb rate (3740fps for 190A8 at sea level), at least at low level, higher the 190As seem to climb too slow. But they seem to be reaching the best substained climb at slower speed. They are not really running at higher boost, may be the gauge is simply indicating a wrong conversion between ata and "MAN.

If you have time, take the following reference points of real 190A8 full loaded and compare them to AH 190A8:

sea level: 3740 fps
6k: 3149 fps
15k: 2952 fps
18k: 2466 fps
21k: 1968 fps
25k: 1525 fps

Bringing this thread around once again, My vote goes to the Spit VIII.
It has a very similar performance to the Spit IX LF, in some ways better.
The wing is not clipped, but improved and stiffer giving enhanced roll rates.
The aircraft was available in 1943 and was suited for tropical conditions.
It was very interesting to carry out the flight trials at Rechlin with the Spitfire and the Hurricane. Both types are very simple to fly compared to our aircraft, and childishly easy to take-off and land. (Werner Mölders)

Well the situation is a bit more sticky than described here and may well end up being one of those times when you better watch what you wish for. I do plan to do quite a bit of work in the performance modeling of planes to try and smooth out inconsistencies. So I'm willing to completely remodel the performance on the A-5. But if I'm going to take the RLM data as the basis of the model, then I'm going to work with all of the RLM data and not just a single data point. Much of the RLM data, particularly in climbing, is inferior to the current AH model.


Posted by Pyro in the other thread. So acordingh to Pyro, if he will work after RLM charts, as you guys want him to, the 190 will climb worse then it does now.

So when you say the 190 quite closely matches real numbers, what charts do you go after?

The 190 is my favorite plane, and as for the charts I have seen the climb rate matches quite nicely when it comes to ft/min but I think you two are misstaking when you think the 190 will be changed for the better once Pyro remodells it after the RLM charts he's got. That is what I've made out from the other thread atleast.

As for Spitfires, I agree on adding more of them, spit VIII would be very nice IMO aswell as a clipped wing 9. Another later version of the Seafire would be nice aswell!

Sorry for further strenghtening the hijack attempt here, let's bring it over into the other thread again...

i had plenty of times when i was engaged by a horde of planes (10-15 or more) which i had got out with about 7 kills.



Why do I seriously doubt this. 10-15  to 1 and you kill 7? Not even the best pilots in AH would accomplish this I am pretty sure.

Just did a very quick test, our 190A8 full of fuel and with 4 guns is doing 3500 fpm at sea level, real one with same configuration 3740 fpm. Why do you thing it will be worse than actual one??

Nashwan,

Your numbers are plain wrong on the 190. The 190A1 had the exact same climb best rate as the 190A3. 16.5 Meters/sec. best climb.


I thought those were the figures I gave, quoting you as the source?

Quote
Not only that you are looking at ONE set of numbers for ONE altitude that was the very best that plane accomplished.


For the Spit, the figures I gave hold true up to 9,000 ft for 16 lbs, about 15,000ft iirc for normal rating. I've repeatedly said I don't know the full 190 performance figures.

Quote
Now like ANY airplane this changed with altitude. So which Altitude are you taking the spit climb rate from, what altitude is the spits best climb and what altitude is the 190's best climb? Plane performance is not just a simple ONE set of numbers.


That's why I specified the altitude range for the Spit figures.

Quote
Remember there is a difference between SPEED and RATE.


Of course there is.

I made a simple comment to someone's "complaint" that the Spit V could outclimb the 190A in AH. I said it should be able to.

Obviously that might not hold true for all altitudes, but then again it might. The 190 wasn't noted for it's high alt performance, after all. But, like I said, I don't know the full climb figures for the 190.

I've seen a scan of an original doc that shows figures for a 190A5, at 1.32 ata 2450 rpm (climb and combat).

It shows 15 m/s at sea level, rising to 15.3 at approx 1 km, dropping to about 12 at 2.5 km, then dropping to 11 at 5.5 km, and 1.5 at 10 km. I don't have the full details about the condition of the plane, or any futher details about the test.

Comparing that to the Spit V at normal rating, which held about 16.4 up to 4.6 km, 14 at 5.5 km, 3.9 at 10 km, the Spit on normal rating wins all the way.

I don't have combat rating figures for the 190s, but I think there's broad agreement it wouldn't reach 4,000 ft/min.

Quote
BTW the Summer of '42 was called the Focke Wulf Summer by the RAF. This is because the FW-190 had complete domination in performance over the Spit Vb.


I've never disputed that the 190 was a better fighter than the Spit V. I merely pointed out that the Spit V in AH outclimbing the 190 was, by and large, correct.

Quote
When Faber, thru a mistake in navigation, accidently landed on an RAF base in England the British got their FW-190.


He didn't land at an RAF base in England. He landed at RAF Pembrey, which is not far from where I live, and my grandmother worked there during the war. I can assure you it's not in England.

Quote
The only advantage the Spit V had was turning.


And climbing.

Don't forget, the RAF did climbing trials with the Spitfire running at normal rating, the 190 running on WEP. Only later on did the A4 gain the increase in power that made the old wep rating the new climb and combat rating. Even then, the independent tests of 190s and Spit Vs found no real difference between a Spit V on normal rating and a 190 on 1.32 ata.

Edit: I didn't want to post the scan of the 190 climb figures in case the person I got it from had asked me not to (I had no idea where the pic came from).

However, a search for the filename found it on the UBI boards, it was originally posted by Butch. http://ubbxforums.ubi.com/6/ubb.x?a=tpc&s=400102&f=63110913&m=807101562&r=745102962#745102962

Speaking of 190s..

 has anyone tested the roll?

 The figures I get for both As and the F, is about 2.8 seconds for full 360degrees aileron-only roll at 300mph IAS, 1000ft altitude. Seems a bit too slow - I thought it was supposed to be about 1.8 seconds for full 360 at that speed.

I think it has been proved that the AH roll rate of the 190 is a tad slow.
Not that it would make it any better, my feel is actually that the 190's roll rate is uncomfortably fast!
In real life however, that would definately make a bit of a difference.
Errr...Nashwan,,,you from Wales? Southern?
I spent some time on a farm in CLWYD ;)
My great uncle also was trained at LLandow.

RAE and NACA measured maxium rate of the roll ie peak rolling speed during roll. I have a some German measurements for one 360 deg roll and here are some  examples:

Fw 190 400km/h 3,2s
Bf 109F 390km/h 4,5s
Bf 109H 400km/h 6s
